Data Access
This dataset contains 2.5 second measurements of the magnetic field data from the triaxial
fluxgate magnetometer and position measurements from Explorer 34 spacecraft in several different coordinate
systems. These data were not well documented. Time is most likely in columns 25-27. Time is given
approximately every 20 s. For each time there are frames (packets of data) 1, 3, 5, 7, 9, 11, 13,
and 15. For each frame there are a set of magnetic or position vectors. Mostly likely a frame occurs
every ~2.5 s. Note that two columns appear to have been lost because the descriptions of the
columns are not clear. Note that some of the data files are corrupted. The stop time given for
those files is the available last good time.

Description of the format and data in the 2.5 s resoluton triaxial fluxgate magnetometer data.
Explorer 34 triaxial fluxgate magnetometer data.
Satellite Identification.
Orbit number
0 = no sequence clock corrections, no frame time corrections applied to this file, there data is "quick-look".
1 = Phase I sequence clock corrections and frame time corrections have been applied to this file, but final correction have not been made, therefore, data is "quick-look".
2 = Phase I and Phase II sequence and frame time corrections have been made to data on this file.
0 = no orbit data included on this file. Fill characters are used in orbit item locations.
1 = "final" orbit data included on this file.
2 = preliminary orbit data included on this file.
3 = predicted orbit data included on this file.
The documentation available suggests that this column is the Experiment Tape Number and the next
column is the Analysis date. The data do not support that description. It is not clear what these values
are supposed to be. Column 25 Appears to be a year and the documentation is off from here to the end.
Columns 25-27 appear to be a time measuement for data. There is a time measurement taken every approximately 20 s,
then a position and magnetic field measurement every frame which is assumed to occur every 2.5 s.
The documentation decribes this value as a decimal day. The data do not support that statement.
Possible flag values are not clear.
Possible flag values are not clear. The documentation suggests the flags may be:
0 = Undetermined
1 = Poor quality
